Abstract (en)

[origin: WO2011072894A1] The method according to the invention for operating a PFR lime kiln comprising at least two shafts, which each have a preheating zone, a firing zone and a cooling zone, and a cross-over channel connecting the two shafts, consists substantially of the following method steps: both shafts are operated alternately as a burning shaft and an exhaust gas shaft, combustion air and fuel are fed to the burning shaft, wherein a corresponding flame length is formed and the hot gases developing in the burning shaft reach the exhaust gas shaft via the cross-over channel, wherein at least one parameter of the hot gases characteristic of the formation of the flame length is determined by a direct or indirect measurement in the region of the cross-over channel, and the ratio of fuel to combustion air is controlled depending on said parameter in order to set a predetermined flame length.
